Northern Alberta epicenter for rare coyote-borne tapeworm: U of A doctor
'We've now identified over 40 cases in Alberta, and there's several more throughout other parts of Canada, but Alberta seems to be a bit of a hot spot.' Coyote savours the return of spring on April 23, 2025, in Edmonton, tossing a small rodent in the air before chugging it down in this photo taken near the Alfred H. Savage Centre. Rodents are the conduits for tapeworm larva hatched from tapeworm eggs shed by coyotes. PHOTO BY MEMORY ROTH A forty-fold increase in a Canadian strain of coyote-borne tapeworm that can cross to the human population is causing concerns for doctors in northern Alberta. Echinococcus multilocularis is a zoonotic parasite that resides quite harmlessly in coyotes, foxes, wolves— even domestic dogs and cats, but the symptoms in humans are enough to make you wash your hands, rinse, and repeat if you shake a paw.

'We haven't had it as an issue in Alberta and Canada for too long, but over the last several years, it's certainly been emerging and concerning,' Waldner said. Current diagnosed cases put the risk as low — one in 100,000 Albertans. The first was identified in 2013 in Edmonton, and the majority of Alberta cases are in the northern half of the province. Mice and voles perpetuate the disease by eating eggs shed in canid dung and then being consumed by a predator. The disease was probably inadvertently imported from Europe in a dog or fox, which aren't required to be dewormed, and does not cause obvious symptoms in the host coyote, fox, dog, or cat.

The spread According to a May 2022 bulletin from Office of the Chief Medical Officer of Health, posted on Alberta Health's MyHealth website, the disease caused by the tapeworm, alveolar echinococcosis (AE) spreads animal-to-person but not person-to-person. 'People can be infected by E. multi by accidentally swallowing tapeworm eggs from contaminated food or water, or from handling infected animals,' it reads. Alberta Health said the common ways of getting AE include eating foods (usually wild berries and herbs) or drinking water that has been contaminated with the stool of an infected coyote, fox, dog, or cat. 'Touching, petting, or handling a household pet infected with the tapeworm, then accidentally swallowing the tapeworm eggs by touching your mouth. Infected pets can have tapeworm eggs in their stool and their fur may be contaminated. This advertisement has not loaded yet, but your article continues below. 'Handling animals like coyotes, foxes, or dogs as part of your job or hobby (e.g., trappers, veterinarians, veterinary technicians),' the site said. Waldner said typically voles or mice eat the eggs, which turn into larva, at which point the mammals prey on the rodents, and the larva hatch into tapeworms. 'We as humans become infected by inadvertently taking the place of the rodents, so somehow, coming into contact and consuming those eggs that are passed in the feces,' Waldner said. Likely sources are vegetables or fruits in the garden, or trappers who are coming in close contact with animals, he said. The coyotes are the likeliest transmitters in northern Alberta, he said, adding there are around 2,000 in Edmonton's river valley. Alas, the eggs are 'super robust.' 'They can resist extremely cold temperatures, so our winter won't kill them off,' he said. This advertisement has not loaded yet, but your article continues below. For a human, the tiny larvae cause lesions in the liver — more like an expanding tumor with necrotic centres — but it doesn't stop there. 'It kind of behaves like a cancer and can metastasize to all over the body. And it can also spread locally and then basically throughout the liver and into adjacent organs and structures,' Waldner said. AE can metastasize to the brain. It's a medical problem that needs to be treated, Waldner said, although he's not aware of any fatalities from the parasite among his patients. While symptoms may include pain or discomfort in the upper belly, weakness, weight loss, symptoms mimicking liver cancer or liver disease, it can be hard to diagnose. Blood serology tests can be inconclusive, showing previous exposure and not necessarily current infection. Ultrasounds are expensive and not always conclusive. This advertisement has not loaded yet, but your article continues below. In many cases, the masses formed by the lesions might not exhibit symptoms unless they block a bile duct, and may go unnoticed until the host gets a liver scan, which gets biopsied. Then it's the good news-bad news scenario: 'Well, it's not cancer.' Waldner said with treatment, people do well and can survive for very long periods of time. Ideally, they'd have it surgically removed. Otherwise, they're on lifelong medication to control the infection. The preferred medication isn't Health Canada approved, so requires special authorization for use and importation, he said. 'But we know that in the absence of treatment, like if someone was not treated for whatever reason, it can be very severe and fatal,' he said. Ounce of prevention The Alberta Health site recommends good hand hygiene like washing hands with soap and water after touching pets, and before touching food. This advertisement has not loaded yet, but your article continues below. Wash or cook wild picked foods such as berries and herbs carefully before eating them. Talk to your veterinarian about ways to prevent E. multi tapeworm infection in your pets. Do not allow your pets to eat rodents or other wild animals. Keep your pet clean. Some dogs will roll in wild animal stool and can then spread tapeworm eggs from their fur to the home environment. For those dealing with wild animals in their profession, wear disposable gloves if you are handling a coyote, fox, or other wild animal (dead or alive).

Urgent warning to dog owners who let their pets lick them after woman catches horror parasite
PET WARNING Urgent warning to dog owners who let their pets lick them after woman catches horror parasite Click to share on X/Twitter (Opens in new window) Click to share on Facebook (Opens in new window) PET owners have been warned of the deadly consequences of letting their pets lick them after a pregnant woman developed a massive parasitic cyst in her abdomen. The 26-year-old, who is 20 weeks pregnant and from rural Tunisia, complained of having stomach pain before doctors unearthed huge cyst in her pelvis. Sign up for Scottish Sun newsletter Sign up 1 Pet owners have been warned against letting their dogs lick their faces Credit: Alamy Hospital staff swooped in a performed emergency surgery to save the unborn child before it burst. It was revealed to be a hydatid cyst - the result of a parasitic infection from a tapeworm that causes cysts in your liver and other organs. The most common form is Echinococcus granulous, and it's often caught by herbivore animals such as sheep or cattle and then transferred to carnivore's animals such as dogs and cats. It can get accidentally transferred to humans via contaminated food by an ova of a parasite. Dr Aimee Warner, resident veterinarian at pet insurance company Waggel, has issued a warning to pet owners on the back of the case. "Ideally, dogs should not lick faces, especially around the mouth or eyes, as a matter of health," she told "Humans are not infected by the adult tapeworms within the dog, but instead ingest Echinococcus eggs passed in dog feces by accident. "If a dog has fecal soiling on its mouth or coat and then licks someone, there is a potential — albeit rare — for transmission." UK THREAT It comes after experts sounded the alarm over the surge of a "neglected" parasite that can cause deadly liver failure. Alveolar echinococcosis (AE) is a rare parasitic disease that spreads from animals to humans and is "of increasing concern worldwide" - but the recent rise in cases has sparked fears that it could reach the UK. The dangerous dog attack capital nestled in the Welsh valleys The "silently progressing and infiltrative disease" is caused by the parasite Echinococcus multilocularis, known as the fox parasite as it tends to infect foxes, as well as dogs. While animals won't usually show any signs of infection, the parasite can cause serious illness in humans, who may pick it up from contact with fox or dog faeces or handling contaminated plants, soil or berries. When the parasite enters the body, it can cause tumour-like growths - usually in the liver - that expand slowly over 10 to 15 years, until they cause symptoms such as stomach pain, weight loss and signs of liver failure. Left untreated, the tapeworms may spread to other organs and can be fatal. The World Health Organisation (WHO) previously listed AE as one of its 17 most "neglected" diseases in 2014, calling for more to be done to control it. Swiss scientists have now revealed that cases of AE, though still rare, increased nearly three times over in a 30 year period. They also revealed that the parasitical disease - once contained in Europe, China, Japan and Siberia - is now spreading to parts of Canada and the United States. "Previously non-endemic regions such as North America and eastern central Europe are reporting an increasing number of AE patients," University Hospital Zurich scientists wrote in a report published by the US Centers for Disease Control and Prevention (CDC). So far, there have been no known domestically acquired cases of E. multilocularis in the UK, meaning it has only been brought in from someone who has travelled. But as cases of the disease are increasingly spotted European regions, it has stoked fears that the parasite may infect animals and humans in the British Isles.
